After writing this I wondered myself how sick would it be to be able to walk around in robes or togas. There must be a reason that kind of clothing has had so much success.
There's a reason people stopped wearing them: toilets. Robes are fine when you can pop a squat and drop a deuce on the roadside, but are a hassle when you have sit down.
My theory is it was horses but we don’t use horses anymore
